Southbound - I don't know how to attach a link to a previous post. But I can tell you Jazzgal's post on speaking to the owner of Dinghy's Beach Bar was posted on 11/12/2023, titled Dinghy BB&G Service Charge/Mumbo Jumbo. In that post she suggested to the owner that there should be no service charge.
Like I said before there was no service charge on our bill yesterday.
For your information our bill yesterday came to $270.00 because we bought a bunch of t-shirts, tank tops and a hat. The suggested tips on the bottom of the bill was based on that amount!! We did tell the bartender we were going to tip 20% on the food and drinks but not on the clothing purchases. He agreed.
